Rotary Evaporator

A rotary evaporator is a machine used for the evaporation of liquids at low pressure. It is used in the laboratory to perform a variety of tasks, such as solvent removal, liquid fractionation, isolation of organic compounds and concentration of solutions. Although a rotary evaporator is a useful tool, it also represents an occupational safety hazard. Because the device operates at low temperatures and pressures, it can produce cold steam and condensation, which can lead to burns and frostbite. In rare cases, the device can also explode. For these reasons, it is important to take a few safety precautions when using a rotary steamer.

Rotary evaporator in operation

At Kalstein we have the ideal rotary evaporator, which is commonly used in the laboratory to distill or purify liquids. It can also be used to distill pure organic compounds. It is a relatively simple piece of equipment consisting of an evaporation chamber, a vacuum unit and a condenser. The evaporation chamber is equipped with a heating plate and has an inlet for the liquid to be distilled. The vacuum unit is connected to the evaporation chamber and the condenser. The condenser is filled with cold water or ice and is connected to the vacuum unit.
